[llvm] [ExecutionEngine] Use DenseMap::insert_range (NFC) (PR #133847)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/133847

We can safely switch to insert_range here because LR starts out empty.
Also, *Result is a DenseMap, so we know that the keys are unique.
